I got the TH3D magnetic flex bed sheet. Made to adhere to your heat bed, then use a steel/spring steel sheet to make a flex bed. I got it a while ago but was hesitant to install it as it seemed kinda weak in strength, but .. well, watch the vid . :)
Magnetic sheet, you can also get the flex/Spring sheet from them and make a full setup/kit.
